Be itlinow'n 'that I; ANDERS -LASS'EN Ban- I mnsnm a subject of the King of Denmark,4 residing vented certain new and.

at B rzedstrup, Denmark," have inuseful- Improvements `in Pulsators for MllkingfMa'chines, of

which the'following is a act'description. The invention relates to a pulsator for Vmilking machines in which themilkingcup 'consists of hrm casing.

The drawing shows a sectional View of an embodiment o f4 the invent-ion.4 Under the milkingcup-proper'is arranged an elastic casing'arranged in a the cast mouthfpiece'c of the pulsator, into one si e of which mouthpiece 1s screwed a tube e'- which'is in connection with .the vacuum. reservoir, and through which the a1r is sucked through the channel c from the holes d in the bottom vof the bottom-piece. @n the shaftc at its lower endis arranged a small airturbine fon the-oblique wings of which `acts the air current from the holes a?, whereby the shaft-cis rotated at a. great speed. In order to regulate the speed a flywheel g is further arranged lon the shaft. The shaft 'also carriesa pinion meshing which latter b movement-to the wheel Z,the upper shaftend 7a of which isbored out in its longituf dinal :tion so deeplyas tomake the valvepp-ning a on .one side ofthe shaft correspond to the valve-openings o and p in the-mouthpiece c, which openings lead'outf ward and to the interior of the milking-cu respectively. The cavity ofthe shaft m 1s so that in the space a: will now arise vacuum.

.im adj valve.

Having now described my said invention y a pinion cgister with the hole 'p,

' connection between the and in what manner the same is to be performed'wha't I claim and desire to secure by Letters Patent of U. S. Americais :l

1.. In'a milking machina' the combination with an inelastic casing, of anelastic casing mounted therein forming an annular chamfull,`clear74 and eX-- lb e to connect the interior ofthe elastic cas-A er between saidcasings', 'a'lnilkway'adapt ing with 'a vacuum reservoir, means for alternately connecting 'the annular chamber with the ymilkway and the atmosphere, whereby suction and atmospheric action are alternately communicated to the annular chamber-, and means operated by the suction for operating said last-named means. l

2. Inr a millnngmacl'iine, the combination with an vinelastic casing, of an elastic casing mounted therein formlng an annular chamber betweensald caslng,

Voir, an air turbine mounted in the base and adapted to be operated by the air suction therethrough, a rotary passage through said base, and connections between said valve and said air turbine whereby'tlfe former is caused to be rotated chamber between 4the casings and between said chamber and the atmosphere, for the purpose set forth.

' 8. ln a milklng machine, the combination with an lnelastlc casing, of anelastic casing mounted therein forming an annular chamber between said caslngs, anaperturedl base for said easmgs communicating therewith,

vamilkway through said base adapted to connect the interior of the elastic casing'with a. yacuum reservoir, a series of shafts'mounted inthe-base, apertures in the hase 'through which air is drawn, an air-turbine, and. a flywheel mounted upon .one of the shafts, means for communicating. motion'from said first-named shaft to the other shafts of the series, one of saidshafts extending through t e upper portion of the base and bored through a portion of interiorof the base and the milkw'ay whereby the suction through sai ay causes air entering the base `to actua the turbine carrying with a vacuum reservalve mounted in a' its length, a valved shaft :md through 'the gem' connections the In witness whereof,' I have subscribed my remaining Shafts, whereby the bored Shaft sgnat1\1'e`1`n the presence of two witnesses. is cnueed '1h its revolutions to successive y Y open and close communication between the ANDERS LASSE BEMHELSEN' milkway and the annular chamber between Witnesses: the oasngand between-said chamber and VIGGO BLOM, the atmosphere, for Jche purpose s'et forth.
